    Answer:

    the answers the correct one is a  4

    Explanation:

    The centripetal acceleration is by

               a = v² / R

    angular and linear velocities are related

               v = w R

    let’s substitute

               a = w² R

    for initial condition

               a₀ = w₀² R

    suppose the initial angular velocity is wo, suppose the angular velocity doubles

               a = (2w₀)² R

               a = 4 (w₀² R)

               a = 4 a₀

    when reviewing the answers the correct one is a
